Radiant Floor Heat, Treated Posts, and “Missed” Screws

Today the Pole Barn Guru answers reader questions about radiant floor heat, properly treated posts for in ground use, and how to fix screws that did not hit the framing materials.

In Floor Heat System InstallationDEAR POLE BARN GURU: I am trying to make a decision on radiant floor heat. The internet has a lot of opinions from a lot of people who are trying to sell one type or the other. Where can I find unbiased information to make an educated decision between electric and hydro systems and how can you get budget estimates for each? BILLY in GOODLETTSVILLE

DEAR BILLY: I have found your best information is going to come from www.RadiantOutfitters.com 1.877.855.2537 they will give you the straight story and not try to sell you anything you do not need.


DEAR POLE BARN GURU: I live in Louisiana. High humidity, normally higher temps. Perfect for the termites. Am I correct in saying that the posts will be placed in the ground? No termites will eat those posts as long as the post is properly treated. How can I guarantee I am getting properly treated posts, because no company will say they have not properly treated wood? TODD in PONCHATOULA

DEAR TODD: For ease of construction and best structural integrity properly pressure preservative treated columns are best embedded into ground. To insure you are getting properly pressure preservative treated wood for structural in ground use, look for end tags on columns with UC-4B on them. UC-4A treated lumber is not adequate for structural in ground use. Pre-construction termite treatment is also an excellent preventative plan: https://www.hansenpolebuildings.com/2019/09/pre-construction-termite-treatment/.


DEAR POLE BARN GURU: I had a contractor build a small metal building that I plan to make my house. After he left I noticed several places where he screwed through the sheets but missed the metal c channel, leaving holes. Some of them are in the roof and some in the walls. I called him back for warranty and his crew used silicone to patch it. So later I sent him a text about it. He said he would come by so we could discuss it. It’s been a month and I still haven’t heard from him. What can I do to get this fixed and how should he go about the repair? CINDY in TYLER

DEAR CINDY: Your challenge is why I always encourage clients to require a performance bond (https://www.hansenpolebuildings.com/2019/11/performance-bonds/). You also should have withheld final payment until a thorough inspection of your building was done, including a punch list of non-conforming issues. Some states require contractor registration, including bonding to give client’s a financial recourse against defective workmanship. Sadly for you, Texas is not one of these states.

Silicone is not an approved fix for ‘shiners’ (screws through steel into air) or holes in roofing or siding. Your only approved fix is to put screws through steel cladding into a solid block of wood on inside.

Your quickest way to get action is going to be to spend a hundred dollars or so to have a construction attorney send a registered letter to your contractor, demanding satisfactory repairs within a reasonable time frame. If this builder has no real assets, chances are he will ignore it entirely, as he knows he has little to fear from losing in court. Ultimately you may need to hire yet another contractor to do your repairs.

Best of luck to you.



Starting from the Ground Up- UC-4B Treated Columns

Starting From the Ground Up- UC-4B Treated Columns

Decades ago, when I began training a sales staff for Momb Steel Buildings (my 1990’s post frame construction company) I developed an outline we called, “From the Ground Up”. Just as implied by its name, this training went through features and benefits of a typical post frame building, starting with ground line and working upwards.

In this and subsequent articles, features and benefits will be described relevant to a typical Hansen Pole Building kit package with double trusses placed upon widely (most commonly every 12 feet) spaced columns.

FEATURE: Structural building columns pressure preservative treated for in-ground use.

BENEFIT: Pressure preservative treated to a UC-4B rating, these columns are warranted against decay for as long as you are building owner!

WHAT OTHERS DO: Hansen Pole Buildings provides post frame building kit packages in all 50 states, so we know how difficult obtaining properly pressure preservative treated columns can be. Many local lumberyards and even big box lumber dealers inventory pressure treated columns rated for “Ground Contact” rated only to a UC-4A level of chemical retention. They can’t be used structurally in-ground according to Building Codes!

Speaking with these providers and being told ‘everyone’ in their area uses UC-4A rated columns for post frame buildings adds to frustration levels!

WHAT WE DID IN 1980: Lucas Plywood and Lumber was providing ungraded 6×6 columns pressure preservative treated to .60 pcf (pounds per cubic foot) or refusal with CCA. The catch in this was “or refusal” meant there was a lot of CCA untreatable lumber (primarily Douglas Fir) was being sent to treatment plants. Being unable to take a CCA treatment and was, for practical purposes, merely painting lumber green with chemicals!

An excellent article written by Sharon Thatcher editor of Rural Builder magazine about Pressure Treatment Beyond CCA can be viewed here: https://www.hansenpolebuildings.com/2016/01/pressure-treatment-beyond-cca/.
